CLAMP FOR SHOE-STANDS.

Application filed October 10,1919.

To all whom it may concern Be it known that I, Grouse VVnIss, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Clamps for Shoe- Stands, of which the following is a specification.

This invention relates to improvements in clamps for shoe stands, particularly adapted, though not necessarily limited in its use for holding the shoe securely upon the stand while the shoe is being cleaned or polished, and has for its object the provision of an improved clamp by the use of which the shoe or foot is prevented from slipping upon or off of the stand.

A further object is to provide an improved device of this character adapted to automatically compensate the varying sizes and styles of shoes.

A further object is to provide an improved device of this character adapted to grip or clamp the heel of the shoe, thereby obviating the danger of marring the shoe upper.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings illustrating this invention, and in which;

Figure 1 is a side elevation of an improved device of this character constructed in accordance with the principles of this invention and showing the same in position for use.

Fig. 2 is a View similar to Fig. 1 showing the position the parts will assume when a 'shoe having a larger heel is placed upon the stand.

adapted toengage. A clamp member 13 is pivotally supported intermediate its ends as at 14 upon the stand 10 and this -.lamping member is preferably provided adjacent its upper end with a heel engaging portion 15 that is preferably slightly con; ave to engage the outer portion of the heel and cooperates with the shoulder 11 to clamp the heel therebetween. The pivot 14 of the clamping element 13 is preferably offset as shown so that when the clamping member is released it will automatically drop into the position shown in dotted lines in Fig. 1 to assume an inoperative position. The end 16 of the clamping element is provided with a recess 17 ad acent its ends for a purpose to be set forth.

Cooperating with the clamping member 13 is an operating member 18 which is pivotally connected as at 19 to a shiftable fulcrum'20, and the pivot 19 extends in'a direction substantially parallel with the pivot 1a of the clamping element 13. This fulcrum is shiftable in directions transverse to the pivot 19 other end abuts a shoulder 25 of the ful-.

crum. A fastening device preferably in the form of a bolt is arranged on the outside'of the casing and passes through a washer 27 and has threaded engagement as at 28 with the ends of the shank for holding the parts together. in order to prevent the fulcrum from rotating, any suitable means may be provided such, for instance, as a pin and slot connection which may be formed by the ends of the pivot 19 adapted to move within slots 29 in the casing wall. The element 18 is preferably offset as shown more clearly in Figs. 3 and 5 to form a bearing portion 30 which is adapted to enter the seat 17 in the clamping element 13 to hold the latter in an operative position. This portion 30 also moves against the inner face of the end 16 of the clamping element to move the latter about its pivot in one direction. The portion 30 is also adapted to engage a stop or shoulder 31 on the stand 10 to limit the movement of the operating element in the opposite direction.

The normal position of the parts is shown in dotted lines in Figs. 1 and 2 and when the shoe is placed upon the stand with the heel engagingthe shoulder 11, the operating element 18 is moved from the position shown in dotted lines to the full line position in Figs. 1 and 2. This will swing the element 13 about its pivot 14 until the end 15 engages the heel and a further movement 01" the element 18 in the same direction will cause the portion 30 to enter the recesses 16 to stop the element 18 and thereby clamp the heel of the shoe. In Fig. 1 there is shown a shoe with a comparatively small heel clamped in position but in Fig. 2 the shoe is provided with a larger heel. Under these circumstances v the operation of the clamping mechanism is the same as above described, but inasmuch as the element 18 has a fixed degree of movement with respect to the clamping element 13, it will be manifest that the clamp 13 would not be held in its clamping position unless the fulcrum of the'element 18 is changed. This is accomplished by means of the structure shown in Fig. 5. When the end 15 of the element 13 contacts with the heel, the movement of the element is arrested but the movement of the element 18 continues and during this continued movement the fulcrum of the element 18 will be shifted by the element 13 inasmuch as it will force the fulcrum 20 to be shifted in the casing 22 against the stress of the elastic member 23 until the parts assume the position shown in full lines in Fig. .2. When the clamp is released, the elastic member 23 will cause the fulcrum to assume its normal position as shown in Fig. 1.

With this improved construction it will be manifest that shoes having varying sizes of heels maybe eiliciently clamped and held with this device, and this is accomplished by reason of the fact that the degree of movement of the clamping element 13 about its pivot may be automatically varied while the degree or" movement of the element 18 with respect to the clamping element 13 remains approximately constant.

l/Vhile the preferred form of the invention has been herein shown and described, it is to be understood that various changes may be made in the details of construction and in the combination and arrangement of the several parts within the scope of the claims without departing from the spirit of this invention.

What is claimed as new is 1. In combination, a shoe stand having a shoulder adapted to be engaged by the shoe heel, a clamping element pivotally mounted intermediate its ends, one end of the element cooperating with the shoulder to clamp the heel therebetween, the said pivot being disposed out of alinement with the ends of said element whereby the first recited end of the element will tend normally to assume an inactive position, the other end of the element having an open recess, a pivotally supported operating lever having shoulder adapted to engage and move the clamping element in one direction about its pivot, said shoulder being adapted to enter the recess to lock the said element and lever in fixed relation, and a shiftable fulcrum to which the lever is pivoted.

2. In combination, a shoe stand having a shoulder adapted to be engaged by the shoe heel, a clamping element pivotally mounted intermediate its ends, one end of the element cooperating with the shoulder to clamp th heel therebetween, the other. end of the element having an open recess, a housing connected with the stand, a fulcrum movable in the'housing and having a shoulder, an elastic element disposed between said shoulder and the housing and tending normally to move the fulcrum in one direction, an operating lever pivotally connected with the fulcrum and also movable with the fillcrum, and'means on the lever adapted to engage and move the clamping element about its pivot, the said means being also adapted to enter the said recess to lock the said clamping element in an active position.

3. In combination, a shoe stand having a shoulder adapted to be engaged by the shoe heel, a pivotally'mounted clamping element cooperating with the shoulder to clamp the heel therebetween, a pivotally mounted operating element, adapted to move the clamping element into clamping relation with the shoulder, and means whereby the clamping element may be caused to clamp heels of diiierent sizes by moving the operating element approximately equal distances. v

4:. In combination, a shoe stand having a shoulder adapted to be engaged by the shoe heel, a pivotally mounted clamping element cooperating with the shoulder to clamp the heel therebetween, a pivotally mounted operating element for moving the clamping element into clamping relation with said shoulder, means whereby the extent of pivotal movement of the clamping element in one direction may be varied while the degree of movement of the said operating element with respect to the clamping element remains approximately constant and the crating against the recessed end of the clamping element to render the same active, the said shoulder being adapted to enter the recess to hold the parts in locked relation.

6. In combination, a shoe stand having a shoulder adapted to be engaged by the shoe heel, a clamping element pivotally supported intermediate its ends, one end co6pcrating with the said shoulder to clamp the heel therebetween, the other end having a recess, a pivotally mounted operating element, said element having a shoulder operating against the recessed end of the clamping element to render the same active, the said shoulder being adapted to enter the recess to hold the parts in locked relation, and means compensating the varying sizes of heels.

7 In combination, a shoe stand having a shoulder adapted to be engaged by the shoe heel, a clamping element pivotally supported intermediate its ends, one end cooperating With the said shoulder to clamp the heel therebetween, the other end having a recess, a pivotally mounted operating element, said element having ashoulder operating against the recessed end of the clamping element to render the same active, the said shoulder being adapted to enter the recess to hold the parts in locked relation,

and a yieldable fulcrum for the said operating element.

In testimony whereof I have signed my name to this specification on this 22 day of August, A. D. 1919.
